LA CRESCENT, MN (WXOW)—La Crescent is working on an ordinance to combat the Emerald Ash Borer that has recently infected two trees in the city.

The ordinance will affect home owners with infected trees, if they are notified of an infestation they have a couple of options.

"They will either have to agree to treat the tree, remove the tree," Bill Waller, La Crescent City Administrator said. "If they do neither of those options, most likely then the city will go through a process and remove the tree and then put those charges on their property."

The ordinance will be introduced for the first time at the city council meeting on February 11.

The Emerald Ash Borer is a small green beetle that can be hard to spot on a tree.

Easier to see are it's d shaped exit holes and zig zagging path on the trees trunk.

Whether you see it yourself or not experts say they are in the area and now is the time to begin combat.     

Over 25 years ago, Ed Koegel bought an ash tree for his yard that's been going strong ever since.

But now, the Emerald Ash Borer is threatening it's life; and has infested a tree at Veterans Park near his home.

"I want to save that tree because it's beautiful," Koegel said. "It shades our home. Our lawns are green yet because they didn't burn up this summer that tree saved them you know."

Koegel is hoping to save his tree by treating it with one of four insecticides on the market.

"They all do work in certain instances but which one works the best? I can't answer that," Ray Pigati, Research Scientist Minnesota Department of Agriculture said.

Pigati said you have to look at ash trees on a case by case basis and suggests you call an arborist for advice.

"What you're going to need to do is evaluate your tree and determine whether or not it is a good tree to keep opposed to if you want to cut it down," Pigati said. "If it's in poor health, already infested with the Emerald Ash Borer, those would be good candidates where you just want to cut it down."

Even though Koegel has been warned that his tree is suspicious he is determined to save it.

"I intend to have it treated," Koegel said. "I don't care what it costs me because it's worth it to me."

Pigati said the best time to treat your tree is in the spring; he said if he was a La Crescent homeowner with an ash tree, he would consider all of his options soon, and make a decision before spring.
